The last time i did when i was bored with petrol in the cottage yard,wait for it...............it left a stain,Lol.
Soap powder dry scattered on to the stain, leave 30 mins absorbs surface oils. Add little water to a paste and brush in. Jet off, no need for conditioner. Smells good even if it doesn't work.
Have you tried this one? https://www.halfords.com/motoring/e...-degreaser/gunk-driveway-clear-1l-678128.html
Andy, no, but I always have a large tin of old style Gunk in the garage, also really like the smell from a hot engine cleaned with the stuff, reminds me of my youth on a GS550. I thought Gunk did something for floors or drives but could not find it in a cursory look earlier
I’ll post up a few pics when I get home. That way we can see the difference of before and after. Will try the different variants of gunk and see how it goes There are two areas so I’ll try a different product/method on each
OT8, use it all the time to clean large oil spills at work, if it works there, it'll work on your blocks. Cleany Uppy Oily Shit Link
If you created more Oil patches - you could test all suggested methods and do a cost / effectiveness comparison Next thing - start of a You Tube channel - and a consumer product testing empire! Or an oil stained drive - one of the two. I would do it but I just have gravel.
Gravel is easy simply load your bath with two buckets at a time, soak in mild caustic soda solution and drain and rinse. Continue until all gravel is clean or the white van arrives with the nice doctors.
Has anyone suggested baking soda & white vinegar? It's certainly not a massive area to scrub' (cheers for pic)
